WHY -FERTILIZE TECHNICAL DATA

SALES HINTS 
A farmer's soil is much like a bank account, i.e., in order to maintain a balance 
(fertility) deposits (fertilizer) must be made to equal withdrawals (crops). We 
know crops remove all of the big three, i.e., nitrogen, phosphorons and potash, and. 
the only common sense program is to replace these elements to maintain production 
and quality. 
Fertilizer sales are most gratifying in that they nearly always result ina feeling 
on the part of the farmer that he has been done.a favor since the response speaks 
for itselt. Generally speaking, a survey of results throughout the United States 
during recent years shows a return of five dollars for each one invested in fertil-— 
izers. Even in times when farm products were bringing low prices, fertilizer in- 
vestment showed a return of three to one. When this is the situation, the use of 
fertilizer is even more important in order to show a profit. In other words, quality 
is the answer here, 
Evidence of fertilizer response has been demonstrated time and time again to the 
farmer until now it is no longer a product that requires testimonials in order to 
sell, 
NOW, A KNOWLEDGE of basic fertilizer chemicals and their action, is necessary to 
merchandise fertilizer accurately and profitably. Next issue, we'll discuss the 
various chemical components and attempt to analyze the problem somewhat.
